Forensic document examination of electronically captured signatures

摘要

Heidi H. Harralson considers the use of biodynamic electronic signatures by which a person provides a signature in electronic format that is reproduced on the screen as a representation of their manuscript signature, and analyzes the procedures used in the forensic analysis of such system, indicating that not all systems produce reliable information to support forensic opinions, and that examiners are failing to understand the need to analyze the digital data.
